• The electrode maintenance concept takes separate inputs for welding gun
no. 1 and welding gun no. 2 into account

• In Stop tip dress or Tip life expired, only a program without Weld on
(internal or external) can be run.
• The function Initial dressing can be activated via timer parameter.
When this function is activated for a specific electrode a „Tip Dress
Request" will come immediately after the „Tip replaced" input signal.
• The lamp test function is activated via the Lamp test input. The following
outputs will become high if the lamp test is active:
• UI controller active
• Timer ready
• Timer fault
• Welding fault
• Tip dress request electrode 1
• Tip dress request electrode 2
• Prewarning electrode 1
• Prewarning electrode 2
• End of stepper electrode 1
• End of stepper electrode 2
• With fan control wired to X4/13-14
• "Fan ON" if heat sink temperature >=55°C
• "Fan OFF" if heat sink temperature <=55°C
• When the weld timer has been switched on, it assumes that the welding
gun is in prelift position.
To avoid the potential risk of the solenoid valve closing at initial program
start from the prelift position, the welding gun first has to be moved to
working position via the "Zangenex_Vorhub" (Welding_gunsx_Prelift) input.
The timer will not respond to the start signal until the closing of the gun has
been completed.

Prop-switch

The output „ Prop-switch " can be used e.g. to switch over the analog pressure
output for an operation with two welding guns. The switch-over is performed
according to the following pattern:

The inputs „ Acknowledge tip dress gun 1" and „
Acknowledge tip change gun 1 " are related to the
electrode selected via the inputs „ Gun code
(gun1)".
The inputs „ Acknowledge tip dress gun 2" and „
Acknowledge tip change gun 2 " are related to the
electrode selected via the inputs „ Gun code
(gun2)".
The inputs „ Acknowledge tip dress gun 1" and „
Acknowledge tip change gun 1 " are related to the
electrode 1.
The inputs „ Acknowledge tip dress gun 2" and „
Acknowledge tip change gun 2 " are related to the
electrode 2.
